bug#22624: [bug-coreutils] coreutils-8.25: big success, but problem on GNU/Hurd

[Nelson H. F. Beebe]

Thanks, Paul, for hurdtest.c and the subsequent tiny patch to it.
Here is the test on my GNU/Hurd system on virt-manager + QEMU-KVM
on top of CentOS 7:

$ cc hurdtest.c && time ./a.out
file=/dev/zero
CHR
st_size=9223372036854775807
st_blksize=8192
st_blocks=8
cur_offset=0
end_offset=9223372036854775807
pagesize=4096

file=/dev/null
CHR
st_size=0
st_blksize=1048576
st_blocks=0
cur_offset=0
end_offset=0
